TPO Silicone

Apply KoolFlex silicone over prepared, adhesion-tested TPO to form a continuous weather-resistant surface. TPO Silicone focuses on waterproofing and standing-water resistance while retaining the serviceable membrane underneath.

Consider this option for low-slope TPO where water retention and prolonged sunlight are important selection factors. A successful adhesion test is essential before committing to the coating.

Design and specification coordination

Use these checks to connect the product record to a complete, project-specific assembly. The manufacturer documents and approved construction documents govern where they provide more specific requirements.

• Confirm membrane type, nominal thickness, reinforcement or fleece construction, color and roll dimensions.
• Coordinate the roof deck, vapor control, insulation, cover board and attachment method as one tested roof assembly.
• Verify adhesive or fastener compatibility, seam-welding requirements, perimeter enhancement and details at penetrations and edges.
• Check wind-uplift, fire and code listings for the complete assembly rather than relying on membrane properties alone.
• For recover work, document the existing roof, moisture survey, substrate preparation and separation-layer requirements.

Submittal and field verification

A useful product record should allow a reviewer to trace what was specified, approved, delivered and installed. Include the following items when this product is proposed or verified.

• Use the exact product name and manufacturer identifier on the submittal; do not substitute a similar family name.
• Attach the current product data sheet and the applicable installation, safety, approval and warranty documents.
• Record selected options such as size, thickness, profile, color, finish, reinforcement and attachment method.
• Identify the tested or approved assembly and list each adjoining component needed to reproduce it.
• At delivery, compare labels and revision dates with the approved record and archive superseded files instead of overwriting them.

Selection, installation and existing-roof checks

Confirm the exact product name, generation and configuration before using any value on this page. Check the roof substrate, slope, attachment or adhesive, reinforcement, edge and penetration details, accessories, tested assembly and local approval that apply to the project. For an existing roof, compare labels, package records, original submittals and physical dimensions; appearance alone is not enough to identify a product.

Your roof substrate

TPO stands for thermoplastic polyolefin. Your roof uses flexible membrane sheets with heat-welded seams and detailed flashings around edges and penetrations. A coating restores the surface of a serviceable membrane after repairs; it does not replace failed seams, wet insulation or inadequate attachment.

Where to use this system

Consider this option for low-slope TPO where water retention and prolonged sunlight are important selection factors. A successful adhesion test is essential before committing to the coating.

Preparation and adhesion

Identify the TPO membrane and existing repairs, then clean the surface and complete adhesion tests. Repair seams, flashings and penetrations before coating. Select the primer for the tested membrane and coating combination. P-301 is a TPO-compatible primer option; the approved system schedule determines where it is needed.

How the coating layers work

Clean and repair the TPO, test adhesion and use the specified primer wherever required. Complete compatible detail work and apply KoolFlex Premium Silicone to the selected film build. Use compatible silicone for subsequent coating repairs or recoats.

Coating thickness

Specify the minimum cured silicone thickness for your chosen assembly and allow separately for primer and detail treatment. The KF-600 sheet has conflicting coverage and wet-film figures. Its 20-mil NSF entry is not a roof-warranty thickness schedule; use the corrected roof-system application schedule.

Guarantee options

KF-600 KoolFlex Premium Silicone offers full-system limited warranty options from 5 to 20 years. Select the written option for your roof, then confirm the required coating build, preparation, inspections and maintenance. A component sheet alone does not establish your project’s coverage.

Care and recoating

Inspect the roof at least twice a year and after severe weather or work on rooftop equipment. Keep drains clear, check flashings and penetrations, and repair damage with compatible materials. Confirm the surface preparation and compatibility requirements before any future recoat.
